SPECIFICATION forming part of Letters Patent No. 244,497, dated July 19, 1881.

Application tiled February 19, 1881. (Model.)

To all whom t may concern Be it known that I, HENRY C. TAYLOR, a citizen of the United States, residing at Mount Vernon, in the county of Jefferson and State of Illinois, have invented certain new and use ful Improvements inyPumps; and I do hereby',

declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the-same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in Which- Figure l is a longitudinal section through the pump-cylinder, discharge-pipe, and sliding cut-off. Fig. 2 is a perspective of one bracket and also one head of the cylinder detached from other parts of the pump. Fig. 3 is a detached view of the discharge-pipe or pistonrod and piston-head cut-oil', a part of the pipe or rod' and sliding cut-ofi' being broken away; and Fig. 4 a vertical sectional view of the pump-cylinder, discharge-pipe, or piston-rod.

and sliding cut-oft', and of an outside cylinder may be inclosed.

My invention has reference to double-acting force-pumps; and it embraces a pump-cylinder proper provided with perforated heads, seats for fitting against each head at different times, whereby rst one head and then the other may be opened and closed; a discharge-pipe passing through the cylinder and provided with apertures for the passage of water from the cylinder into the discharge-pipe; a cut-off which serves as a piston head to divide the cylinder into ltwo chambers, and at the same time as a cut-'oft' to alternately close communication between one chamber and the dischargepipe, and open communication lbetween the discharge-pipe andthe other chamber, whereby as the several parts are operated Water is admitted from the source of supply Iir'st into indicates the pump-cylinder proper, which is provided with the perforated heads B,which are screwed thereon, as shown, or bolted thereto in any approved way. A discharge-pipe, C, the lowerpart of which may be solid, as shown,

'passes longitudinally through the cylinder and its heads, and in the form shown has a free longitudinal play. This discharge-pipe, between its ends within the cylinder, has attached to it two iian ges, a af, which are formed as part of the pipe, or secured thereto by solder or by set-screws, so as to be adjustable. The pipe between these iianges is provided with open-in gs, as shown, so as to effect a communication between the interior of the pipe and th'e cylinder. Ablock or annular cut-off, D, is fitted around the pipe C, between the ilanges a a', so as to have a free up-and-down movement between the flanges, against one or the other of which it bears, so as to form a close joint when moved up or down against the same. In diameter it is such that it will extend beyond the edges of the iianges and fit snugly against the inside wall of the pump- .'cylinder, so as to form a water-tight joint, in

order that it may act as a piston-head when operated. I prefer to make the diameter of the openin g in the cut-od' considerably larger than the circumference of the pipe around which it fits, so as to leave a space between the cut-off and the pipe, into which the water may enter, so as to pass into the dischargepipe through all the openings, as illustrated in Figs. 1 and 3; but the cut-off can be made to dt quite near 'to the pipe, so that the water will pass through only those openings in the pipe which will be between either the top or bottom face of the cut-off and flange c or a', according as the cut-off is against one or the other of said flanges. l

When the parts 'are constructed and arranged as described the discharge pipe is free to move up and down within the cylinder and the latter to slide along the pipe.

The pump-cylinder and discharge-pipe, or piston-rod,77 as it may be termed, are held in position by two brackets, E and E, which also serve as seats'against which the heads of the cylinder are alternately bron ght to bear in operating the pump, and by which the perfora- IOO tions in the cylinder-heads are closed when the parts are in contact. These seats may be iianged and held to a base, F, by screws, bolts, or other suitable means. The faces of these seats next to the cylinder-heads, and the faces of the heads themselves, are made so that,

when the faces of the heads and of the seats are brought together the perforations in the heads will be effectually closed. The seats are placed so far apart that when the pump-cylinder is placed between them there will be left space enough for the cylinder to have a longitudinal play, the length ot' which may vary to suit circumstances, but that allowed the pump illustrated in the drawings is about one-eighth of an inch.

For operation the pump is submerged in a well of water or other source ot supply, and there held by any suitable means. In operation on the downstroke ofthe discharge-pipe, which serves for a piston-rod, the lower head of the cylinder bears against the seat E', and the cut-olil D bears against the upper flange, a, whereby the perl'orations in the lower head are closed, and communication between the lower chamber of the cylinder and the dischargepipe is opened, so that the water will pass from the chamber through the pipe to the point of delivery, the cut-oft' now serving as a piston or plunger to force the water from the chamber. At the same time communication is opened between the upper chamber and the well through the upper cylinder-head, while it is closed between that chamber and the discharge-pipe by the cut-off D, so that the upper chamber willbe filled with water while the lower one is emptied. On the upstroke of the piston-rod or discharge-pipe the action is just the reverse of that described-that is, the upper head -of the cylinder is brought against the seat E, and the cut-ott' D against the flange a', whereby communication is opened between the upper chamber and discharge-pipe and lower chamber through the lower cylinder-head and well, and closed between the lower chamber and pipe and upper chamber andwell, and so the parts alternately act during the operation of pumping.

The piston-rod or discharge-pipe can be reciprocated by the operator taking hold of the pipe itself and moving it up and down, or by a lever or rod extending from the top ot' the well to a point below the pump-cylinder, where it may be connected to the piston-rod in any suitable well-known way.

A pump constructed according to the foregoing description dispenses with the valves heretofore used, is cheap of production because of the few parts composing it and their simplicity of construction, which also render it less liable to get out of repair and make it more durable, and while it possesses the above advantages it is positive in its action and highly satisfactory in the discharge of its function.

Such a pump as has been described, instead of being submerged in a well of water, may be inclosed within a vessel or tank, to which the water is supplied, and in which the pump will work in like manner as when submerged in a well of water. I will now illustrate and describe such an application without claiming the details ot construction. The application is illustrated in Fig. 4, in which the parts corresponding to those shown in the other iigures are indicated by the same reference-letters, and as the construction and operation of the corresponding parts are the same a detailed description thereof is unnecessary, and therefore I will described only the additional features. The pump is inclosed in a water-tight vessel or tank, J, which may be strapped to its supporting-bed or held thereto by bolts or screws passed through flanges cast with the tank and into the bed. The heads of this tank, which are the seats E E', are screwed, bolted, or otherwise secured to the body ot' the tank, and the joint at the point where the discharge-pipe or piston-rod passes through the head is packed in any suitable manner, as illustrated in the drawings. Water is furnished to this tank from the water-main or other source of supply through the pipe Gr, which is provided with a check-valve, H, and also a stopcock, I. The tank may also be provided with a stop-cock at any convenient point, for the purpose of drawing oi' the water preparatory to taking off one of the heads for the purpose of cleansing the tank from all sediment that may have settled therein.

For operation the tank is filled with water, and then when the pump is operated, as hereinbefore described, the wat-er is pumped from the tank to the desired point, the same as from the well.

When the tank J is air-tight, or substantially so, and the pump isoperated, so as to exhaust the air from the tank, the water will be raised from the well, by suction or atmospheric pressure, through the supply-pipe G, whereby the tank is kept supplied at all times with water and the pump is always ready for work. Of course if the water-supplyis in elevation above the tank J no suction will be required to raise the water to the tank, and the latter need not in that case be air-tight, and the check-valve in the supply-pipe can be dispensed with.

rlhe piston-rod pipe can be operated by hand or mechanical power from above or below the tank, many means of doing which will suggest themselves to the mind of a skilled mechanic.

Instead of reciprocating the piston-rod pipe in operating the pump it may be stationary, in which event the pump cylinder and seats would be reeiprocated along the piston-rod pipe, which could be done by moving to and fro the bed or base plate F, with the pump-cylinder and seats connected thereto in one case, and the tankJ and pump-cylinder in the other case.

The pump can be used for pumping other inids than water from a vessel or other source,

and can be made of metal, glass, or other suitable material, and there may be deviations from the details of construction of the several parts, without departing from the spirit of my invention.

Having described my invention, what I claim is- 1. In a pump, the combination of a cylinder provided with openings at its ends, seats for fitting against each end from the outside at different times, whereby first one end and then the other may be closed, a discharge-pipe passing through the cylinder and provided with `openings for the passage of liquid from the cylinder into said pipe, a cut-off which serves to divide the cylinder into two chambers and to alternately close communication between one chamber and the discliergepipc and open communicationbetween said pipe and the other chamber, whereby the parts are adapted to operate substantially as set forth.

2. The cylinder A, provided with openings for the admission of a liquid, in combination With seats for alternately opening and closing said openings, a pipe for the discharge of the liquid from said cylinder, a cut-off for controlling the passage of the liquid into said pipe, first from one section of the cylinder and then from the other section, and a close tank, J, surrounding cylinder A, and provided with means for admitting the liquid, substantially as set forth.

3. The cylinder A, provided with openings for the admission of a liquid, in combination with means for alternately opening and closy ing said openings from the outside of the cylinder, a pipe for the discharge of the liquid from said cylinder, and a cutoff for controlling the passage of the liquid into said pipe, rst from one section of the cylinder and then from the other section, substantially as set forth.

4. In a pump, the combination of a longitudinally-moving cylinder provided with openings at both ends, seats for closing said opening as first one end of the cylinder and then the other comes in contact therewith, a pipe for the discharge of the liquid from the cylinder, and a cut-off for controlling the passage of the liquid intov said pipe, first from one section of the cylinder and then from the other section, substantially as set forth,

5. The piston-rod pipe C, perforated, and provided with flanges above and below the perforations, and having a sliding cut-off between said flanges and extending beyond the edges thereof, substantially as set forth.

6. rIhe piston-rod pipe C, perforated, and provided with flanges above and below the perforations, and having a sliding cut-off between said flanges and extending beyond the edges thereof, in combination with a cylinder, A, having openings at its ends, and seats for alternately opening and closing said openings, substantially as set forth.

7. The movable cylinder A, having perforated heads B, in combination with seats E E', and perforated discharge-pipe C, provided with sliding cut-off D, substantially as set forth.

In testimony whereof I aix my signature in presence of two witnesses.
